Fascia relaxation is a simple and effective relaxation method, which can relax the tense muscles of the calf. You can generally try to massage with a foam roller. Put the foam shaft on the back of the calf and roll it back and forth until the calf muscles become soft. Fascia dredging can promote the blood circulation of the legs, accelerate the fat metabolism of the legs, and make the legs more compact, thus achieving the effect of shaping.
